ICD-10 Code E11.620 – Type 2 diabetes mellitus with diabetic dermatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.620 – Type 2 diabetes mellitus with diabetic dermatitis
What it is
E11.620 identifies type 2 diabetes mellitus complicated by diabetic dermatitis. Use it when the record links the skin condition to diabetes rather than to another cause.
Clinical signs
Clinical features vary; refer to documentation. Records may describe diabetic skin changes such as dry, itchy, inflamed, or cracked skin, but you should code only when the provider documents diabetic dermatitis.
When to use this code
Use E11.620 when the provider states that the patient has type 2 diabetes with diabetic dermatitis or a diabetes-related skin inflammation. The note should connect the dermatitis to diabetes. If the skin problem is documented as unrelated, code the skin condition instead and do not assume diabetic causation.
Do not use for
Do not use this code for dermatitis without a documented diabetes link, or for other diabetic skin complications such as ulcers or infections. Check documentation if the skin diagnosis is unclear.
Coding tip
Look for explicit wording that ties dermatitis to diabetes before assigning E11.620.
